SEPARABLE HINGE.

SPECIFICATION forming part of Letters Patent No. 720,304, dated February10, 1903. Application filed March 22, 1902. Serial No. 9941l- (N0 l-l T0all whom, it may concern.-

Be it known that I, RUDOLPH G. WINTER, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inSeparable Hinges; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My present invention has for its object to provide a separable hinge ofimproved construction especially adapted for use on screendoors, butadapted for use also on stormdoors and other places.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Figure 1 is a face view or side elevation of a hinge embodying theseveral features of my invention. Fig. 2 is a view corresponding to Fig.1, but with nearly all of one section of the hinge broken away and thoseportions which are shown beingturned into different relative positions.Fig. 3 is a horizontal section on the line 00 00 of Fig. 1. Fig. 4 is aplan View of the hinge; and Fig. 5 is a side elevation, with some partsbroken away, of one of the hinge members.

The numeral 1 indicates as an entirety the relatively fixed member ofthe hinge-to wit, that member which would be secured to the door casingor frame. This hinge member 1 is provided in its ends withlaterally-projecting perforated hinge-ears 2, the perforations of whichstand in axial line. The ears 2 are provided with upper and lowersegmental notches 3, which run into the perforations thereof and formlateral openings considerably less than one hundred and eighty degreesin extent. The said ears 2 are further provided with outwardly-extendedsegmental cam-lugs 4, which incline in both directions. At itsintermediate portion the said member 1 is formed with alaterally-projecting resistance block or plate 5, which is curved at itsinner portion and preferably turned inward to form a heavy head 5, asbest shown in Fig. 3. At its extremities thesaid resistance-block 5 isalso preferably provided with horizontally-extended ribs 6, as bestshown in Figs. 1 and 2.

The relatively movable member of the hingeto wit, that member which issecurable to the door-is formed by a hollow channel-- like body providedat its ends with projecting hinged ears 8. The hinged ears 8 areprovided with trunnions 9, which to make the hinge reversible, as willhereinafter more fully appear, extend both upward and downward. Thetrunnions 9 are adapted to fit within the perforations of the ears 2,and the ends thereof are reduced or cut, as shown at 10, to adapt themto be inserted laterally through the segmental notches 3 of said ears 2.The ears 8 are provided with laterally-projecting lugs 11, which areadapted for cooperation with the cam-flanges 4. of the ears 2, as willbe hereinafter more fully described. Within the seats 7 of the caseformed by the body of the hinge member 7 is a laterallyremovablelongitudinally-extended bolt 12, around which is Wound a double-endedcoilspring 18, the ends of which are anchored to the said hinge member7at 14 and the intermediate portion of which works through a perforation15 in said'body or case-forming section and is extended so as to form alever or arm 17. The transversely-extended section at the free end ofthe said lever or arm section 17 affords a bearing on which is mou nteda roller 18. The said transverse portion 17 is preferably divided at thecenter of the roller, as shown in Fig. 5, so as to permit the roller tobe quickly placed in working position and removed.

I The hinge members 1 and 7 are provided with the ordinary screw-holes19, through which the screws may be inserted to secure the said parts inthe one instance on the door casing or frame and in the other to thedoor.

The hinge is a reversible hinge-to wit, capable of use on a doorarranged to swing either toward the right or toward the left. Thisreversible feature is made possible by the trunnions 9, which projectboth upward and downward from the respective ears 8. To illustrate: Inthe drawings the hinge is shown as so put together as to permit the doorto swing toward the left. As is obvious, if

the door were to swing toward the right the hinge member 1 would have tobe turned upside down or end for end. Then the member 7 would also haveto be turned upside down or end for end, which would of course bringthose two trunnions 9, which, as illustrated in the drawings, projectupward and are idle, into cooperation with the perforated ears 2 of thehinge member 1. In other words, it is always those trunnions 9 which areturned downward that cooperate with the perforated ears 2. It is alsoevident that with this arran gement the ears 8 must always stand'abovethe cooperating ears 2, so that the door and the hinge member 7 aresupported by the said ears 2. At the same time the door, together withthe hinge member 7, may be lifted from working positions. It is alsoevident that when the hinge is reversed, as above stated, so as topermit the door to swing toward the right, the cam-lug 11 and cam-flange4, which in the drawings are shown as thelower members, will then becomethe upper members and will be brought into cooperating relation.

By reference to Fig. 5 it will be noted that the perforation 15 has anentrance slit or passage 15, which runs out at one edge of the case orbody 7. With this construction when one prong of the spring-arm 1 7 hasbeen forced laterally out of engagement with the roller 18 it may beturned outward through the slit 15, and in this way both sections of thespring may be readily detached or removed from working position. Whenthe sections of the spring are placed in working position and when thehinge-section 7 is detached from the cooperating hinge-section 1, theprongs of the said spring-arm 17 will strike the shoulders 15, formed atthe junction of the slit 15 with the perforation l5, and will thereby beprevented from being thrown out of proper position.

The action of the hinge when applied as shown in the drawings will besubstantially as follows: Then the door is closed, the hinge memberswill stand as shown in Figs. 1 and 3 by full lines, and the spring 13will force the roller 18 tightly against the inner face of theresistance block or plate 5,and will thereby yieldingly hold the doorclosed. When the door is swung open only to an ordinary extent or isgiven such swinging movement as it would be given by a person passingthrough the doorway, it will be automatically closed by the spring 13and cooperating action of the roller18 on the resistance-block 5. When,however, the door is forced open nearly to its extreme limit andsubstantially as indicated by dotted lines in Figs. 3 and 4, the roller18 will engage the outer surface or back of the head 5 of the resistanceblock or plate 5 and will yieldingly hold the door in its open position.Furthermore, when the said door and. hinge member 7 are swung open totheir extreme position (indicated in Figs. 3 and 4) the upper cam-lug 11will be caused to travel over and then be carried to a position inwardof the cooperating upper flange 4, so that the gravity of the door andof the said hinge member 7 causes the said cam members 11 and 4 tocooperate and yieldingly hold said door in its open position. As isevident, to impart the initial closing movement to the door onlysufficient force will be required to cause the cam-lug 11 to move overthe cam-flange 4, under which action it must of course raise the doorslightly. The initial closing movement being imparted to the door, therest of its movement will, as has already been stated, he completedautomatically by the force applied from the spring 13. Where the hingeis to be applied to a storm-door, the spring device will not usually bedesired, and hence a simple hinge member having only the ears 8 andtrunnions 9 may be employed, and such members may be left permanentlysecured to the storm-door. On the other hand, the spring-equipped hingemembers may be left permanently secured to the screen-door. With thisarrangement it becomes obvious that the screen-door and the storm-doormay be very quickly and easily substituted or interchanged one for theother, inasmuch as the hinge members applied thereto are in each caseadapted for cooperation with the hinge members having a perforatedhingeear and which are left permanently secured to the door casing orframe.

From what has above been said it will be understood that the hinge abovedescribed is capable of considerable modification within the scope of myinvention as herein set forth and claimed.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

1. A pair of separable hinge members, the one having the perforated ears2 with laterally-opening segmental entrance-notches 3, and the otherhaving ears 8 with trunnions 9 projecting in both directions from saidears and en gageable laterally through said notches 3 and insertibleendwise through the perforations of said ears 2, substantially asdescribed.

2. The combination with the hinge member having perforated hinge-ears,at least one of which has a cam-flange 4, of a cooperating hinge memberhaving the ears 8 with trunnions working in said perforated hinge-ears,

a cam-lug 11 on one of said ears 8 cooperating with said cam-flange 4 toyieldingly hold the door open, and a spring device which becomes activeto yieldingly close the door after said lug 8 has been thrown outward ofsaid cam-flange 4, substantially as described.

3. The combination with a pair of pivotally-connected hinge members, onethereof being formed to afiord a spring seat or case and provided withthe perforation 15 with open but contracted entrance-slit 15, and thetwo-part spring 13 located Within the seat or case of said hinged memberand provided with the divider spring-arm 17 equipped with In testimonywhereof I affix my signature the roller 18, which perforation 15 andslit 15 in presence of two Witnesses. afiord stop-shoulders 15 againstwhich the T A v spring-arms 17 strike, and which slit 15 per- RLDOLPHWINTER units of the removal of said arms 17 there- Witnesses:
